In situ XANES study of the influence of varying temperature and oxygen fugacity on iron oxidation state and coordination in a phonolitic melt
Iron oxidation state and environment in magmas affect their phase diagram and their properties, including viscosity and density, which determine magma mobility and eruptive potential. In turn, magma compositio...

The Influence of Glass Composition on Iodine Solubility
Two glass series in the ternary systems K2O−B2O3−SiO2 (KBS) and Na2O−B2O3−SiO2 (NBS) were studied in order to identify the main factors influencing the solubility of iodine. We established that iodine incorporati...

Natural Glasses
Natural glasses have been used since prehistoric times and are strongly linked to human evolution. On Earth, glasses are typically produced by rapid cooling of melts, and as in the case of minerals and rocks, ...

Open AccessPercolation channels: a universal idea to describe the atomic structure and dynamics of glasses and melts
Understanding the links between chemical composition, nano-structure and the dynamic properties of silicate melts and glasses is fundamental to both Earth and Materials Sciences. Central to this is whether the...

The dependence of Raman defect bands in silica glasses on densification revisited
This paper focuses on the densification signature measured by Raman spectroscopy in silica-based glasses. We have studied a pure silica glass and a 25GeO2–75SiO2 binary glass fabricated by plasma chemical vapor d...

Quantification of the ferric/ferrous iron ratio in silicates by scanning transmission X-ray microscopy at the Fe L2,3 edges
Estimation of Fe3+/ΣFe ratios in materials at the submicrometre scale has been a long-standing challenge in the Earth and environmental sciences because of the usefulness of this ratio in estimating redox conditi...

Thermodynamic and rheological properties of rhyolite and andesite melts
The heat capacities of a rhyolite and an andesite glass and liquid have been investigated from relative-enthalpy measurements made between 400 and 1800 K. For the glass phases, the experimental data agree with...
